Kristin Davis to star in NBC comedy

'Happiness' follows woman's year-long quest to become happier

“Sex and the City” alum Kristin Davis is attached to star in and produce a laffer for NBC and Universal Media Studios about a woman’s year-long quest to become happier in her life.

“Chuck” scribe Kristin Newman is in talks with the studio to write and exec produce the pilot. The single-camera project is based on the real-life experience of Gretchen Rubin, a former law clerk for Supreme Court Justice Sandra Day O’Connor, who embarked on a quest to explore the nature of happiness while writing a book, “The Happiness Project,” that was published by HarperCollins in January. Rubin also launched a related blog, happiness-project.com, that piqued Davis’ interest.

Davis will serve as a co-exec producer on the project. Mosaic will co-produce with UMS, with Mosaic’s Jimmy Miller and Dave Fleming, who rep Davis, also exec producing. Lit manager Christy Fletcher will co-exec produce.
